How do you change the headlamps on a 1998 Ford Expedition XLT?

Answer 1

There are clips on the assembly that you have to release, which pull up. The whole light assembly then can be pulled from the front. DO NOT touch the glass portion of the replacement bulb as the oils from your fingers will make the bulb overheat and blow on use. Remove the old bulb, put in the new bulb and replace the assembly (take your time to make sure it lines up straight). Then replace the clips and you're good to go. I know this because I tried to figure it out myself and ended up having a service guy walk me through it so I would know when I had to do it again.

***CAUTION***

The halogen bulb contains gas under pressure. The bulb may shatter if the gas envelope is scratched or if the bulb is dropped. Handle the bulb carefully. Grasp the bulb only by its base. Avoid touching the glass envelope.

è The headlamp bulb should not be removed from the headlamp until just before a replacement bulb is installed. Removing the bulb for an extended period of time may affect headlamp bulb performance. Contaminants may enter the headlamp where they can settle on the lens and reflector. Never turn on the headlamps with the bulb removed from the headlamp.
